Router Interface Operation
Figure 80. Router Source, Router Destination, and Routed Karrera Source
Router signal switching is non-deterministic, as compared to source selec-
tions performed on a production switcher. For this reason, it is better to
choose the desired router source in advance, then switch it on-air using
switcher controls, rather than select a different router source while it is on-
air.
An external router can be configured into levels, to allow the switching of
multiple signals simultaneously. For example, video signals can be orga-
nized on one level, and key signals on another. By specifying both levels
when giving a router take command, both the video and key signals of a
source will be routed to their destinations.
Note Karrera system router take commands are only applied to all router levels.The
external routing system’s destinations must be configured with all router
levels selected.
Router control panels can also protect router destinations from being
changed by other control panels. A protected router destination cannot be
changed by a different control panel, but may be changed by the panel that
set the protection. Protections help prevent inappropriate router source
changes. The Karrera system can be considered a type of router control
panel, and so the Karrera system can protect router destinations. Karrera
system router protect commands are applied to all router levels.
The names of router sources appear on the Karrera system source name dis-
plays. These names originate from the router system, and their text cannot
be changed from the Karrera system. If a routed Karrera source has no con-
nection to the router, an
X appears in place of the router source name. If the
router connection exists, but no source has yet been selected for that desti-
nation (which can occur during bootup),
No Src appears.
